Trihydrogen Nitride Chemical Properties,Usage,Production

  • Description The hydride of nitrogen is NH3, an azane known as ammonia. Nitrogen forms a quasi-like hydride, NH3. It is normally encountered as a gas. However, it does not behave as a typical hydride in that it does not decompose in water to form hydrogen but dissolves in water to form a weak base:
    NH3 +H2O ? NH4+ + OH-
    Ammonia, as used commercially, is often called anhydrous ammonia. This term emphasizes the absence of water in the material. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at -33.3 °C, and solidifies at -77.7 °C (195 K, -108 F) to white crystals. Because NH3 boils at -33.34 °C, the liquid must be stored under high pressure or at lowtemperature. Its solubility in water is 47%(0 °C), 31% (25 °C), 28% (50 °C). Its density is 0.86 g/cm3 (1.013 bar at boiling point), 0.73 g/cm3 (1.013 bar at 15 °C), 681.9 g/cm3 at -33.3 °C (liquid), 817 g/cm3 at -80 °C (transparent solid). It is a flammable gas with a flash point of 11 °C and an auto-ignition temperature of 651 °C. Nitrides of the alkaline earths are generally made by heating the metals in pure nitrogen gas.
